Fixed installations in classified hazardous locations petroleum processing, chemical plants, oilfield production facilities, and high-pressure test labs operating in NEC-classified areas face a combination of requirements that most motorized hose reels cannot meet simultaneously: 5,000 PSI working pressure, explosion-proof motor rating, and 115V AC power compatibility. The Coxreels HP1125-4-100-EA addresses all three on the compact HP1125 Series chassis. A 115V AC, 1/2 HP explosion-proof reversible AC-rectified motor (an AC-powered drive whose incoming supply is internally converted to direct current for the motor windings, enabling powered hose pay-out and retraction from a standard 115V circuit in a classified hazardous location) pairs with the HP1125 Series high-pressure frame electroless nickel plated steel 90° NPT swivel rated for 5,000 PSI service, AFLAS seals for broad chemical and heat resistance, and direct gear drive for quiet, chain-free retraction. For facilities where the standard 3,000 PSI ceiling of explosion-proof reels in this chassis class is insufficient and the working line pressure demands the HP1125 rating, this is the reel that closes the gap without requiring a larger-chassis alternative.

- AFLAS swivel seals fluoroelastomer compound with superior chemical and heat resistance over Nitrile seals, suited to petroleum, hydraulic fluid, chemical, and elevated-temperature service at 5,000 PSI working pressures
- Exclusive low-profile outlet riser and open drum slot design provides a non-crimping, flat smooth hose wrap around the drum
- Heavy-duty CNC robotically spun and ribbed discs with rolled edges for greater strength, durability, hose protection, and operator safety
- Sturdy one-piece, all CNC robotically welded 12-gauge steel A-frame base not bolted for superior reel structure; mounting pattern in base for wall, ceiling, or overhead installation
- Permanently lubricated, self-aligning pillow block bearings for trouble-free, smooth drum rotation over extended service life
- Adjustable tension brake prevents free-wheeling during hose deployment; long-lasting chip-resistant, rust-inhibiting CPC powder coat finish; 2-year manufacturer's limited warranty

Applications
- Petroleum refinery & chemical plant classified installations fixed overhead reel stations in NEC-classified hazardous areas where 5,000 PSI service lines carry petroleum products, solvents, or process chemicals and 115V AC power is available at the mount point
- Oilfield production & processing facilities wellhead areas, compressor stations, and processing plant classified zones where high-pressure chemical injection lines, stimulation fluid hose, and elevated-pressure service require both the HP1125 pressure rating and an explosion-proof motor
- High-pressure test labs in classified environments hydraulic component test facilities and pressure testing stations in classified areas where 5,000 PSI test lines, automatic reel retraction, and explosion-proof electrical equipment are all simultaneously required
- Marine & offshore classified installations vessels and platforms with 115V AC service power in classified zones where high-pressure fluid lines require a compact motorized reel rated for both the working pressure and the hazardous location
- Industrial MRO in classified high-pressure environments plant maintenance stations in refineries and large process facilities where classified-area requirements and 5,000 PSI service lines both apply and 115V AC infrastructure is available
FAQs
Q: What is the difference between the HP1125-4-100-EA and the standard 1125-4-100-EA?
A: Both use a 115V AC, 1/2 HP explosion-proof reversible AC-rectified motor on the same basic chassis with direct gear drive. The difference is working pressure and swivel specification. The HP1125-4-100-EA is rated to 5,000 PSI with an electroless nickel plated steel swivel and AFLAS seals. The standard 1125-4-100-EA is rated to 3,000 PSI with a machined brass swivel and Nitrile seals. For classified-area installations at or below 3,000 PSI, the standard 1125-4-100-EA is the appropriate choice; for classified-area installations requiring up to 5,000 PSI, the HP1125-4-100-EA is required.
Q: What is the difference between the HP1125-4-100-EA and the HP1125-4-100-E?
A: Both provide automatic drum retraction on the HP1125 Series 5,000 PSI frame, but they differ in power source, output, and hazardous-location rating. The -E is a 12V DC, 1/3 HP non-explosion-proof motor suited to standard non-classified environments and mobile 12V platforms. The -EA is a 115V AC, 1/2 HP explosion-proof reversible motor required when the installation area is a classified hazardous location and 115V AC power is available. Choose the -EA when both the explosion-proof rating and fixed AC power infrastructure are present; choose the -E for non-classified 12V mobile applications.
Q: What does "AC Rectified" mean on this explosion-proof motor?
A: AC rectification converts the incoming 115V alternating current to direct current inside the motor housing. This enables reversible operation powered hose pay-out as well as retraction from a standard AC supply and control switch, without requiring a separate DC power source. The motor wires directly into a 115V AC circuit and operates bidirectionally through standard switching, while the explosion-proof enclosure contains any internal arc or ignition to meet classified-location requirements.
Q: What wiring and conduit is required for the explosion-proof motor in a classified location?
A: The motor enclosure carries an explosion-proof rating, but a compliant installation requires that all conduit, wiring methods, junction boxes, and switching devices in the complete circuit also meet NEC Article 501 or 502 requirements for the applicable Class, Division, and Group of the installation area. Coxreels does not publish the specific NEC Class/Division/Group rating for this motor in the catalog motor options chart confirm the motor's specific hazardous location classification with Coxreels before installation, and verify full circuit compliance with a licensed electrician experienced in hazardous location wiring. At 5,000 PSI working pressure, a mismatched installation creates compounding risk from both the electrical and pressure hazards.
Q: Does the reel come with hose included?
A: No the HP1125-4-100-EA ships less hose. The drum accepts 1/2" ID / 7/8" OD hose up to 100 feet. Select hose with a working pressure rating at or above your system pressure (up to 5,000 PSI), rated for your specific media, and compatible with the electroless nickel plated steel swivel and AFLAS seals. In petroleum or chemical service, verify hose compound compatibility with your process fluid before installation. At 5,000 PSI, use assemblies with fittings rated and crimped for high-pressure service.
